Abstract

A wireless communications system including at least one base station operative to communicate with terminals on a plurality of carrier frequencies in repetitive time slots defined thereon is operated by assigning an entire time slot or a spreading-code defined subchannel of a time slot to a terminal based on a communications constraint associated with the terminal. The communications constraint may include a performance requirement, such as an information rate or an error rate, and a signal reception condition, such as signal to noise ratio. According to another aspect, a wireless communications system determines a communications constraint associated with a terminal. The system assigns a time slot, a spreading code, a coding rate and a bandwidth to the terminal based on the determined communications constraint. Preferably, the system assigns a time slot, a spreading code, a coding rate and a bandwidth to the terminal such that at least one of an available bandwidth, a number of available time slots, and a number of available spreading codes is optimized. Related apparatus are also described.
